Hyperlinks Do Not Work In Outlook


2 out of 4 found this helpful.

When clicking on a hyperlink within an email you might get the following error;
“This operation has been cancelled due to restrictions in effect on this computer. Please contact your system administrator.”

This issue is usually caused when there is not a default browser, or the browser is not properly recognized by Windows as being the default browser. The main cause seems to be uninstalling the Google Chrome browser.

Reassigning the default browser

Sometimes the fix is as simple as reassigning the default browser.

  • For Windows 8.1 and 10
    Start -> then type: Default Programs 
    Charms -> Settings -> Control Panel -> Programs -> Default Programs
  • For Windows Windows 7 
    Start -> Default Programs

If you only have a single Internet browser installed in Windows 7, Windows 8.1 or Windows 10, you can also deselect all the defaults for the browser by pressing “Choose defaults for this program”, save the changes and then select them all again.

Resetting the browser

If the above process does not work, you should reset the browser.

For Internet Explorer, this can be done through Control Panel -> Internet Options -> Advanced tab.

For Firefox, open a Run command and type the following (note the spaces); 
Firefox -safe-mode

In the dialog that pops-up select the option “Reset all user preferences to Firefox defaults” and press “Make Changes and Restart”.

Chrome is not included because uninstalling Chrome is generally the cause of this particular problem.
